|Popular magazines||Scholarly journals|
|Use everyday language||Use technical language|
|Written for the general reader||Written for experts by other experts|
|Do not include references to sources of information used to write the article||Include a list of references at the end of the article|
|Generally make only passing references to research, if at all||Often report on research and include descriptions of the methodology used and statistical analysis of the results (articles in the humanities, such as literature or religion, are excepted)|
|Articles are chosen and checked by editors||Articles must pass a review by experts in the same field before publication.|
Note: Scholarly journal articles are not always perfect. Every year many articles are withdrawn because of errors detected subsequent to publication, or because of ethical violations on the part of one of the authors.
Many of the Library's databases have a check-off option for scholarly ("peer-reviewed") journals, making it easy to limit your search to peer-reviewed publications.
The ScienceDirect and MEDLINE interfaces do not have such a checkoff option, but almost every article in these databases is from a peer-reviewed journal. New Scientist is the only popular magazine on ScienceDirect.
